Hot tank for parts degreasing

ABSTRACT

A hot tank for parts degreasing in which a bottom wall is spaced above gas burners which are surrounded by side walls to direct the flow of heat across the bottom wall and up along an outwardly sloping end wall. The degreasing tank contains a degreasing fluid which is heated by the gas burners. Parts degreased in the degreasing fluid can be hung on the end walls so as to be dried by the heat flowing upwardly from the gas burners.

2. Summary of thelnvention A degreasing tank is provided with a bottomwall spaced above the supporting surface and above gas burners supportedon the supporting surface. The tank has side walls arranged around thegas burners to direct the heat from the gas burners across the bottomwall and up along outwardly sloping end walls to heat the contents ofthe degreaser tank. Parts which have been degreased in-the degreasingtank may be hung on the outwardly sloping end walls so as to be dried bythe heat flowing upwardly from the gas burners.

The primary object of the invention is to provide a degreasing tank forparts which will quickly andefficiently heat the degreasing fluid whileproviding a hot gas stream for drying the degreased parts. 7 V

Other objects and advantages will become apparent in the followingspecification when considered in the light of the attached drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of theinvention;

FIG. 2 is a vertical sectional view taken along the line 2-2 of FIG. 1,looking in the direction of the arrows; and

FIG. 3 is a vertical transverse sectional view taken along the line 3-3of FIG. 2, looking in the direction of the arrows.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings indetail wherein like reference characters indicate like parts throughoutthe several fiugres the reference numeral indicates generally adegreasing tank constructed in accordance with the invention.

The degreasing tank 10 includes a pair of generally rectangular uprightside walls 11, 12 arranged in spaced apart parallel relation. The sidewall 11 is provided with a pair of generally rectangular notches 13, 14opening upwardly therein from the lower edge of the side wall 11.

A generally rectangular bottom wall 15 somewhat shorter than the sidewalls 11 and 12 is secured to the side walls 11, 12 in upwardly spacedparallel relation to the bottom edges of the side walls 11, 12. Thebottom wall 15 is positioned above the notches 13, 14 as can be seen inFIGS. 1 and 3.

A transverse partition 16 is secured to thebottom of the bottom wall 15and has its opposite ends secured to the side wallsl I, 12 intermediatethe notches 13, 14.

An upwardly and outwardly sloping end wall 17 has its lower end securedto one end of the bottom wall 15 and its opposite sides secured to theside walls 11, 12. An upwardly and outwardly sloping end wall 18 has itsbottom edge secured to the bottom wall 15 and its side edges secured tothe side walls 11, 12. The end walls 17, 18 have their upper edgesaligned with the upper edges of the side walls 1 1, 12.

A generally rectangular diffuser plate 19 is secured to the side walls 11, l2 and slopes inwardly and upwardly toward the lower portion of theend wall 17 with its upper edge 20 spaced outwardly from the end wall17. A spacer member 21 extends from the upper edge 20 of the diffuserplate 19 to the end wall 17 to assist in maintaining the diffuser plate19 in spaced relation with respect thereto.

A generally rectangular diffuser plate 22 has its opposite ends securedto the side walls 11, 12 and slopes inwardly and upwardly from one endof the side walls 11, 12 toward the lower end portion of the end wall18. The upper edge 23 of the diffuser plate 22 is spaced outwardly fromthe lower portion of the end wall 18 and a spacer member 24 extendsbetween the upper edge 23 and the end wall 18 to support the center ofthe diffuser plate 22.

Gas burners 25, 26 are positioned on opposite sides of the artition 16below the bottom wall 15 and gas conduits 27 exend outwardly therefromthrough the notches l3, 14 to a source of heating gas (not shown). Thetank 10 is welded together to provide a leak proof container fordegreasing chemical fluids contained therein.-

In the use and operation of the invention the gas burners 25, 26 areignited and the products of combustion along with heated air flow acrossthe bottom wall 15 away from the partition 16 and out through the spacebetween the end walls 17, 18 and the upper edges 20, 23 of the diffuserplates 19, 22 respectively. The hot gases flow upwardly along theoutwardly sloping end walls 17, 18 to quickly and uniformly heat thedegreasing chemical fluids in the tank 10. Parts to be degreased aresuspended in the tank 10 from conventional hooks and are left in the hotchemicals until degreasing is complete where upon they are removed andhung on the outer face of the end walls 17, 18 to be dried by the hotgases flowing upwardly therealong to thus prevent rusting of thedegreased parts.

The tank 10 may be drained as required for renewal of the chemicalfluids therein by means of a drain nipple 28 secured in the side wall 11and closed with a cap 29 at the outer end thereof.

Having thus described the preferred embodiment of the invention itshould be understood that numerous structural modifications andadaptations may be resorted to without departing from the spirit of theinvention.

What is claimed is:

l. A degreasing tank comprising a bottom wall having a pair of burnerchambers formed therebeneath, a pair of upstanding side walls secured tosaid bottom wall, a pair of upwardly and outwardly sloping end wallssecured to said bottom wall and said side walls, means for directing hotgases from said burner chambers upwardly along said upwardly andoutwardly sloping end walls, said burner chambers including the lowerportions of said side walls extending below said bottom wall and apartition wall positioned below said bottom wall and extending betweensaid side walls, said means for directing the hot gases upwardly alongsaid end walls comprising a diffuser plate adjacent the lower end ofeach of said end walls and extending between said side walls, saiddiffuser plates sloping inwardly and upwardly and having their upperedges spaced outwardly from the lower ends of said end walls.

2. A device as claimed in claim 1 wherein said end walls are flat andgenerally rectangular in form and said diffuser plates are flat andgenerally rectangular in form.
